Sujira is a great host.
She gave very clear instructions for check in and was quick to respond. She also allowed me to check in early and leave my bags in the room to pick up a bit later when I checked out.
The apartment was very clean and as described. There is a nice gym and swimming pool in the building.
It is about 10-15 mins walk from Saphan Thaksin BTS and central pier for river taxi/tourist boat. Bangrak night bazaar is nearby and there is a great selection of street food and restaurants, also Silom nightlife and Lumphini park are nearby.
